about stainless steel

QS products are made from 304 Grade Stainless Steel which, as you can see from the above table, has the highest resistance to corrosion along with 316 and 316L.The staining character and pit density difference between 304 and 316 is negligible and does not, in our opinion, justify the20 - 30 percent price difference (316 being more expensive).Directly after purchase, satin stainless steel has a tendancy to discolour. This is caused by the oxidisation of the residue of the buffing wax left on the finished surface.Once this is cleaned off by a non-abrasive cleaner such as Handy-Andy, the finish will maintain itself with just an occassional wipe with a mild detergent.
